    This problem appears after the update from 2021.2.4f to 2021.2.5f.
    No bugs in console. Library folder cleared and project reimported succesfully, but no effect. No ideas how to fix this.

    Same problem in default HDRP sample scene in my project.

    Bloom is likely not the root cause, you probably have a NaN or an Inf value and the Bloom is just expanding it

    https://docs.unity3d.com/Packages/c.../manual/Post-Processing-Propagating-NaNs.html

    To confirm the hypothesis you can try and activate the Stop NaN option on the camera settings (or scene camera settings for scene view). If that indeed stops the screen from going black, I suggest tracking down the NaN source.

    If it happens on a completely empty scene/project with nothing custom, feel free to open a bug and we'll look into the source of the NaN

    It's simple model with simple two materials without any custom shaders on it.

    Its clearly not an issue on their end since previous Unity version didn't present this problem in the first place. Happened to me aswell, bloom, reflection probes, refraction and other effects that work perfectly fine and without any performance problem in previous version started making black squares appear in all scenes in latest version. Had to revert back to the former version in which this problem is not present. Stop NaNs did not resolve this and it was not needed in previous version anyway.
